Changes: Chi-To Prototype I

Latest revision as of 05:03, 27 August 2018

Overview

The Chi-To「チト」Prototype I was the first development of the 57mm medium tank project.

Development

ZLrHyge — Experimental 57mm Anti-Tank Gun.

In 1942, Japan began to revise their tank doctrine to a similarity of other leading nations at the time. From this was born 3 tank concepts.

Kō (A)	Otsu (B)	Hei (C)
47mm	57mm	75mm

It was realised that a 47mm tank design would not be sufficient, and the Kō concept was merged with Otsu to become Chi-To.

An experimental long 57mm anti-tank cannon was the selected armament of the new medium tank. It was tested on various tanks, such as the Ho-I, which became a major role in the development of the project in particular. A new hull and chassis were designed to suit the requirements of the project. At the first half of 1944 the prototype was finished, borrowing the turret design of the Ho-I guntank.

Shortly after, it was decided that the new Experimental 75mm cannon would replace the 57mm for all future tank projects. The Chi-To had to be redesigned to fit this standard, and development of a larger turret to house this gun began quickly.

Variants

Chi-To Prototype I

The first development of the Chi-To medium tank, housing a 57mm tank cannon.

Chi-To Prototype II

The second Chi-To prototype. Enlarged turret to fit a 75mm tank cannon.

Chi-To Mass Production Model

The finalized, production Chi-To tank.
